Product Description
This chapter provides a product description of the KZPSA PCI-to-SCSI Storage Adapter. It also
lists the operating standards for the adapter and its electrical and environmental specifications.
1.1
Introduction
The KZPSA adapter (Figure 1–1) is a Peripheral Component Interconnect (PCI)
to Small Computer System Interface-2 (SCSI-2) adapter. You install the adapter
on your computer motherboard through a PCI connector for 32 bit/+5V operation. Each adapter provides connection for one fast, wide differential SCSI bus.
Cabling provides the interconnect between the adapter and a storage device.
The adapter supports up to 15 devices, including RAID controllers. Both 8-bit
differential SCSI bus devices and 16-bit differential SCSI bus devices can be directly connected. To connect single-ended devices, you must use a differentialto-single-ended SCSI bus converter, such as a Digital DWZZA bus converter.
Figure 1–1 KZPSA PCI-to-SCSI Storage Adapter
EK–KZPSA–UG. B01
1–1
KZPSA PCI-to-SCSI Storage Adapter
The adapter’s processor minimizes the SCSI I/O overhead of the host computer’s
processor by interpreting host commands and translating them into specific device commands. This includes support for direct data transfer to host memory,
coding device-specific commands into specific command scripts, and supporting
internal command queues with disconnect/reconnect functionality.
The KZPSA is capable of 32-bit bus master data transfers, including PCI enhanced data transfer commands. The host adapter supports most SCSI-2 functions.
The host adapter supports multithreaded I/O operations, thereby allowing simultaneous operations on multiple SCSI targets or Logical Units (LUNs). In systems
with multiple targets, the Disconnect/Reconnect feature optimizes SCSI bus usage. In systems that have fragmented memory buffers, the Scatter/Gather feature
provides high performance.
In addition to its normal role of SCSI initiator, the KZPSA provides support for
target mode operations. In this mode, the KZPSA can receive incoming SCSI-2
processor commands intended for its locally connected host. This functionality
makes the KZPSA, with operating system support, an integral component in advanced-system configurations such as the high availability DECsafe Available
Server Environment.
The KZPSA has several parameters the user can change to optimize the adapter’s
functionality within the system. These parameters may be changed using the
configuration utility software included with the module. This utility provides the
capability of changing settings on the boards NVRAM without having to make
physical changes to the host adapter board.
Some of the major features of the KZPSA are:
1–2
•
Compliance with Intel PCI version 2.0, ANSI X3t9.2 SCSI-2 Standard, and
U.S. and international safety/emissions standards
•
Fast-Narrow SCSI (8-bit, 10 Mbytes per second, 7 devices)
•
Fast-Wide SCSI (16-bit, 20 Mbytes per second, 15 devices)
•

Configuration Guidelines
Before you install the KZPSA PCI-to-SCSI storage adapter in your computer, you need to become familiar with the configuration guidelines for the host adapter and its SCSI bus. This chapter will help you plan your system configuration. It discusses the SCSI bus configuration, bus
termination and power, and describes bus signals and their functions.
2.1
Configuration Defaults
Your KZPSA adapter has been configured at the factory as follows:
Adapter Attribute
Default
Reason to change
SCSI ID
7
If there are multiple SCSI adapters on the same
SCSI bus.
SCSI Termination Present
Yes
If KZPSA is not at one end of the bus.
SCSI Termination Power
Yes
If too many nodes supply termination power, there
is a potential safety issue because too much current
is available.
SCSI Fast Data Transfer
Yes
If there are single ended segments greater than 3
meters.
SCSI Bus Reset on Boot
No
To allow SCSI bus resets during Boot.
Device Attribute
Default
Reason to change
Wide Negotiation
Yes
If the device is incompatible with wide negotiation.
Synchronous Negotiation
Yes
If the device is incompatible with synchronous negotiation.
Tagged Queuing
Yes
If the device is incompatible with tagged command
queuing.
Disconnect
Yes
To improve single device performance.
EK–KZPSA–UG. B01
2–1
KZPSA PCI-to-SCSI Storage Adapter
These defaults were chosen for optimum performance of the adapter. If they are
acceptable for your configuration, proceed to Installation in Chapter 3. Each of
these attributes, except for termination present, can be changed by using the
configuration utility described in Chapter 6.
2.2
PCI Bus Configuration
PCI Adapters are automatically configured by the power-up software. The
adapter addresses and interrupts are set without jumpers.
2.3
SCSI Bus Configuration
The KZPSA allows direct connection of both 8-bit (narrow) and 16-bit (wide)
differential SCSI bus devices. You can connect up to 15 devices to your adapter.
The total bus length should not exceed 25 meters for a differential SCSI bus.
For the KZPSA to support single-ended devices, you must use a differential-tosingle-ended SCSI bus converter such as the Digital DWZZA bus converter.
With a DWZZA bus converter (16-bit differential to 8-bit single-ended), you can
connect up to 7 single-ended SCSI bus devices in addition to 8 wide differential
SCSI bus devices to the KZPSA adapter. With a DWZZB bus converter (16-bit
differential to 16-bit single-ended), you may connect up to 15 single-ended devices. The total bus length should not exceed 3 meters for a fast single-ended bus
or 6 meters for a slow single-ended bus.
The SCSI ID for the KZPSA adapter is defaulted to 7. If multiple adapters (see
your host system manual for possibilities) are used on the same SCSI bus, the
recommended SCSI IDs of the adapters should be 7, 6, 5, etc. Specific applications, such as Available Server Environment in Appendix B, may make alternative recommendations.
Only one device can use the SCSI bus at a time. When two or more devices try to
use the bus at the same time, the priority arbitration scheme determines which
device goes first and which devices must wait. The SCSI ID priority from highest
to lowest is as follows: SCSI ID 7-6-5-4-3-2-1-0-15-14-13-12-11-10-9-8.
2–2
EK–KZPSA–UG. B01
Chapter 2. Configuration Guidelines
2.4
SCSI Bus Termination
Bus termination is required at each end of the SCSI bus. Typically, the SCSI bus
has the KZPSA adapter at one end and some storage device at the other end. In
this case, you must have termination resistor packs (Z1–Z5, Figure 2–1) installed
in the KZPSA adapter; these are installed at the factory. There should not be any
termination at any of the intermediate devices. If the KZPSA is used in the middle of the SCSI bus, the termination resistors should be removed from that
KZPSA.
NOTE
When connecting a "Y-cable" (BN21W-OB) to the
KZPSA, be sure to remove termination resistors
Z1–Z5 from the adapter. In this configuration, the
KZPSA is no longer at the end of the bus and external termination must be installed.
Figure 2–1 KZPSA Termination Resistor Locations
EK–KZPSA–UG. B01
2–3
KZPSA PCI-to-SCSI Storage Adapter
2.5
SCSI Termination Power
It is normal for adapters, not devices, to supply termination power to the SCSI
bus. The KZPSA adapter is configured at the factory to supply 1.5 amps of termination current. Although each SCSI node may supply termination power to the
bus, a single source from the host adapter is sufficient. No more than four
sources of termination power on a SCSI bus is recommended.
2.6
SCSI Fast Data Transfers
Eight-bit devices that allow fast data transfers will transfer data at rates greater
than 5 Mbytes/sec., usually at the normal 10 Mbytes/sec. rate. The actual speed
is negotiated between the adapter and the device at the start of a transfer. If disabled, this will be limited to 5 Mbytes/sec. This allows for single-ended bus
segments that exceed the three meter fast limit and, therefore, must be speed restricted.
2.7
SCSI Bus Reset-on-Boot
For some high-availability configurations, SCSI bus resets on system boot are not
desired as there may be another adapter on the same bus. This defaults to no
SCSI bus resets sent on the bus during boot, but can be configured to issue them.
2.8
Device Wide Negotiation
Because some older devices fail to conform to the SCSI specification for wide
negotiation, they may not be recognized by the KZPSA unless wide negotiation
is disabled. The adapter default allows wide negotiation.
2.9
Device Synchronous Negotiation
Because some older devices fail to conform to the SCSI specification for synchronous negotiation, they may not function correctly unless synchronous negotiation is disabled. The adapter default allows synchronous negotiation.
2.10 Device Tagged Queuing
Because some older devices fail to conform to the SCSI specification for tagged
command queuing, they may not function correctly if tagged command queuing
is allowed. The adapter default allows tagged command queuing.
2–4
EK–KZPSA–UG. B01
Chapter 2. Configuration Guidelines
2.11 Device Disconnects
To optimize overall SCSI bus performance, the adapter default allows device
disconnects. This means that a device that realizes a need for a lengthy delay before the next data can be transferred can disconnect this operation to allow another device to utilize the bus, and resume it later when the data is available.
This disconnect may also be disabled when there is only a single device on the
bus. By preventing disconnects, performance can be improved as the disconnect /
reconnect protocol time is avoided. When a single device is connected to the
SCSI bus, optimum performance is usually obtained by disabling disconnects.

OpenVMS AXP and OSF/1 Systems
This chapter provides information which is unique to the installation and use of your KZPSA
adapter with either the OpenVMS AXP or OSF/1 operating systems. The information includes
how to verify the physical installation of the adapter in your system and how to modify some
adapter parameters for the console. Some adapter parameters require the use of KZPSA utilities
as described in Chapter 6.
4.1
Software Supplied
Your KZPSA adapter comes with a floppy diskette that contains various tools
used during the installation and verification process as well as the Windows NT
AXP device driver. This diskette is labeled KZPSA Alpha AXP Software. This
diskette is a FAT-formatted diskette containing the KZPSA firmware update
utility (fwupdate.exe) and the KZPSA configuration and diagnostic utility
(cnfgdiag.exe). The diskette also holds a file containing the current firmware in
the adapter. This is shipped in case the firmware in the adapter gets corrupted. It
can be loaded into the KZPSA via the KZPSA firmware update utility. Refer to
Chapter 6, KZPSA Utilities, for more information. Locate your diskette and
make a copy of it now. Store the original in a safe place.
4.2
Completing the KZPSA Installation
After the physical installation, the KZPSA adapter is ready for use. On system
power-on the SRM console requests that the KZPSA adapter execute its built-in
self test (BIST). BIST covers all the components on the KZPSA, excluding the
SCSI Bus and PCI Bus Drivers. If an error is detected on the KZPSA, the SRM
console will display:
KZPSA BIST failed, %S failed (%S = SRAM, OPUS, etc.)
EK–KZPSA–UG. B01
4–1
KZPSA PCI-to-SCSI Storage Adapter
If there is an error, try system power-on again. If the KZPSA error persists, refer
to Chapter 7, Troubleshooting.
NOTE
If the KZPSA passes self-test, no message is displayed at console boot.
Enter "show config" at the console prompt to see if the devices on the
KZPSA SCSI bus can be accessed. This command displays the system configuration as determined by the SRM console during power-up (Refer to your AXP
Systems Documentation.) This display should identify the KZPSA adapter and
an indented list of attached devices.
4.3
KZPSA Adapter Configuration
There are three parameters that you can and may want to change before booting
the operating system. For more information about the parameters, read Chapter
2, Planning your System Configuration. Each of these parameters are changed
using the set command. The parameters are:
• KZPSA SCSI ID
• SCSI Termination Power
• SCSI Fast Data Transfer
If the defaults are OK, and you don’t want to use a KZPSA device as a boot device, you’re done! Boot the system and enjoy. If you want to configure a KZPSA
device as a boot device, go to the last section of this chapter (KZPSA Device
Booting).

The KZPSA adapter supplies SCSI termination power by default. To change it so
that the KZPSA does not supply power, enter the console command as follows:
set pk*0_termpwr #
where:
* is the controller ID from show config,
# = 0 for disable termpwr,
and # = 1 for enable termpwr
4.6
SCSI Fast Data Transfer
The KZPSA adapter is supplied with the speed set to fast by default. The fast
speed is 10 megabytes/second for a narrow SCSI bus and 20 megabytes/second
for a wide bus. The slow speed is 5 megabytes/second for a narrow bus and 10
megabytes/second for a wide bus. These parameters apply to all devices attached
to this adapter. To alter SCSI speed for SCSI devices, enter the SCSI fast command at the console as follows:
set pk*0_fast #
where:
* is the controller ID from show config,
# = 0 for a slow SCSI speed,
and # = 1 for a fast SCSI speed

Release Notes
Mandatory Console Code Update
During the qualification testing of the KZPSA, some critical problems were found with the console code for the
AlphaServer systems. You need to update your systems with the new code provided on the diskettes included with
this option.
If you have an AlphaServer 1000, locate diskette AK-QK57A-CA from the option package. The procedure to be
followed is from the AlphaServer 1000 Owner’s Guide, Order Number: EK-DTLSV-OG.A01, (page 7-5) entitled
"Updating Firmware Using the Diskette Drive". The steps are as follows:
Insert the diskette with the new firmware version in the diskette drive.

Enter the following command at the SRM console prompt:
>>> boot dva0
2.
Load and execute the update utility:
APU-> update
3.
Turn the system off and on.
4.
Confirm the update:
>>> show version
This should report the revisions for SRM as X3.10-3798 and ARC as 4.1-19. The update has successfully completed. OK to proceed! If you have not completed successfully, please refer to your AlphaServer 1000 Owner’s
Guide.
If you have an AlphaServer 2000 or 2100, locate diskette AK-QK58A-CA from the option package. The procedure to be followed is from the AlphaServer 2x00 Loadable Firmware Update Utility User Guide and Release
Notes that came with your system. The procedure starts on page 4-3 with "Booting the Update Utility from the
OpenVMS Diskette". The steps are as follows:
First, insert the firmware update diskette into the system diskette drive and boot the diskette, as shown in the following example:
>>> boot dva0
# NOTE: No colon on DVA0, please
This takes about 2 minutes...
After several minutes the Loadable Firmware Utility menu and prompt “UPD>“ should appear on the VGA (or a
serial line terminal on COM1). If the update utility has booted successfully, then skip to chapter 5.
Continuing at paragraph 5.1, Steps to Update the SRM and ARC Console Firmware
NOTE
The update command under the LFU updates both the SRM
and ARC console.
1.

When the update is complete, exit the LFU.
UPD>exit
4.
Answer No to the question “Do you want to do a manual update[y/(n)]”.
Do you want to do a manual update[y/(n)] n
5.
Reset the system to start running the new console code.
Please reset the system
As the system reboots, it should report the SRM as 3.10-33 and the ARC as 3.5-31. The update has successfully
completed. OK to proceed! If you have not completed successfully, please refer to your AlphaServer 2x00 Loadable Firmware Update Utility User Guide and Release Notes.
Restrictions
•
Miscellaneous - Certain older SCSI disk and tape devices that cannot properly handle wide SCSI transfer
negotiations might not work correctly with the KZPSA adapter. For example, when you use the console
command show config, the system will not display information about these older disk or tape devices, i.e.
RZ58.
To avoid this problem, contact your Digital services representative to verify your device contains the latest
firmware revision and/or run the KZPSA Utility (described in Chapter 6 of KZPSA Users Guide) to disable
Wide Negotiation for the device.
OSF/1 Restrictions:
•
•
OSF/1 supports the use of up to seven SCSI devices for each KZPSA storage adapter.
The KZPSA-BB adapter is supported on DECSafe Available Server revision V TBD or greater. KZPSA-BB
firmware must be revision A04 or greater to work in a DECSafe Available Server configuration.
KZPSA Restrictions:
The CNFGDIAG and FWUPDATE utilities do not support multiple KZPSAs in a AlphaServer 2100 at this time.
The KZPSA configuration and update utilities do not support multiple KZPSAs in AlphaServer 2X00 at this time.
The workaround is to install only one KZPSA at a time and to configure that one module. Configuration information is stored in non-volatile memory so each module can be set up one at a time. After all modules have been
individually configured, all modules may be installed in the system.

Figure B–1 shows a KZPSA adapter configured to indirectly communicate with
six single-ended 8-bit SCSI devices. The DWZZA (bus converter) resides within
the first (SCSI ID 0) slot of the BA350-SA storage shelf. The KZPSA directly
interconnects, by way of a point-to-point cable, to the DWZZA-VA.
NOTE
Refer to your StorageWorks enclosure documents
for specific information on how to configure a Digital
BA350 storage shelf and the installation and replacement of its components.
B.2.1 Single-Ended SCSI Bus Configuration
The BA350 storage shelf contains two single-ended SCSI buses which are internally configured as a single bus. Six 3½-inch half-height 8-bit SCSI devices are
attached to the bus.
B.2.2 SCSI ID Selection
The KZPSA adapter is assigned SCSI ID 7. For the SCSI devices, the device address is selected by its physical location within the storage shelf, with the slot
number equating to the SCSI ID number.
B.2.3 SCSI Bus Termination
The differential bus is terminated at one end by the KZPSA storage adapter
(internally) and at the other end by the DWZZA bus converter (internally). The
single-ended bus is terminated at one end by the DWZZA bus converter
(internally) and at the other end by a terminator board located behind slot 1 on
the backplane of the BA350 storage shelf.

documents for specific information on how to configure an HSZ40/Digital BA350-MA storage shelf
and the installation and replacement of its components.
B.3.1 Single-Ended SCSI Bus Configuration
The BA350 storage shelves are setup in a split-bus configuration by installing the
BA350 internal jumper board behind slot 1 and the terminator board behind slot
5. Each bus shares the same terminator. The HSZ40 contains six single-ended 8bit SCSI ports. The BA350-MA controller shelf is physically configured for a
6x3 bus arrangement. An array of 18 3½-inch half-height devices are attached
across six single-ended SCSI buses. SCSI bus #1 through SCSI bus #6 are accessed through their respective SCSI connectors, mounted at the bottom of the
controller shelf. Cables for these connectors exit through the front of the controller shelf and interconnect directly to the BA350 storage shelves containing the
SCSI devices.
B.3.2 SCSI ID Selection
The KZPSA adapter is assigned SCSI ID 7. The RAID controller is assigned
SCSI ID 6. For the SCSI devices, the device address is selected by its physical
location within the storage shelf, with the slot number equating to the SCSI ID
number.
B.3.3 SCSI Bus Termination
The differential bus is terminated at one end by the KZPSA storage adapter
(internally) and at the other end by attaching a differential terminator to the unused 68-pin p-connector on the tri-link connector located on the disk array controller. The six single-ended buses are terminated at one end by active terminators internal to the disk array controller and at the other end by the BA350’s
terminator board located behind slot 5 within the shelves.

DECsafe Available Server Environment (ASE) Configuration
A DECsafe Available Server Environment provides multi-host access to SCSI
devices and a generic failover mechanism for network-based applications and
system services using a shared SCSI bus. Figure B–3 shows two KZPSA adapters
configured in a DECsafe Available Server environment to communicate with six
single-ended 8-bit SCSI devices.
The DECsafe software monitors the network and the status of the systems and
devices in the DECsafe environment and includes an infrastructure that automatically moves applications from one system to another if a hardware or software failure occurs. For more detailed information about ASE, consult your
DECsafe Available Server documentation.
As shown in Figure B–3, a KZPSA adapter is installed in a PCI Bus slot in each
host system. "Y" cables are connected to the KZPSA adapter in both systems.
One end of both "Y" cables is terminated to terminate the bus. A standard SCSI
cable is connected to the unterminated end of both "Y" cables.
The DWZZA (SCSI bus converter) is installed in the first slot of the BA350-SA
storage shelf. The KZPSA adapters directly interconnect, by way of the standard
SCSI cables, to the bus converter through a tri-link connector block.
NOTE
For this configuration, the internal termination must
be removed from the KZPSA adapters and the
DWZZA-VA bus converter in the BA350-SA storage shelf. Refer to your StorageWorks enclosure
documents for specific information on how to configure a Digital BA350-SA storage shelf and the installation and replacement of its components.
B.4.1 Single-Ended SCSI Bus Configuration
The BA350-SA storage shelf contains two single-ended SCSI buses which are
internally configured as a single bus. Six 3½-inch half-height 8-bit SCSI devices
are attached to the bus.
